TECHNICAL FIELD

The present invention relates to a pin embodiment which enables firing a cartridge in superposed smoothbore shotguns with superimposed barrel within the space called frame and to a safety embodiment.

The present invention specifically relates to a pin assembly and a safety assembly which can be assembled and disassembled easily independently from the mechanical parts inside the frame within shotguns.

PRIOR ART

In our day there are shotguns with superimposed barrel called superposed which the hunters generally use. Said superposed shotguns consist of two superimposed barrels. These are the shotguns which are filled by being broken from the hinge between the barrel and the body via a lever located on the body called as frame and which is ready for shooting.

The systems called superposed smoothbore shotguns with superimposed barrel lowers the parts called hammer by actuating the inner trigger via a selector connected to the trigger and the hammers perform firing by striking against the pins. There is a part called safety on the body in order to prevent bursting. Safety process is performed by moving the safety member backwards.

During the manufacture of the body of the superposed shotgun, discharge is performed in the part called tailpiece. After the discharge process, holes are opened on the lateral surface of the body in order to mount the pin, hammer, inner trigger, selector and other inner parts. These mechanical parts are fixed onto the body via pins.

In the prior art, since the lateral surface of the body is exposed during safety mounting it is mounted from the lateral surface via a pin.

In the prior art, since deformation of the pin is too much, there may be problems such as breaking. When the shotgun is sent to the manufacturing company or technical service for part replacement in such a problem, pins, springs and mechanical arts on the body starting from the stock of the shotgun need to be disassembled.

A professional interference is needed for part replacement in the known state of the art, this causes the repair period and accordingly the cost to increase.

As a result of the researches in the literature, various embodiments can be found relating to said shotguns. One of them is the patent with application number 2013/04544 and with title “Superposed trigger mechanism”. In the abstract of the invention with classification F41A 19/10 the following description takes place: “The invention relates to a trigger adjustment knob relating with the trigger, a trigger adjustment body, trigger mechanism/embodiment on the trigger body on the superposed shotguns bodies, characterized in that it comprises a trigger pull on the trigger adjustment body; a hammer block, hammer spring pins, hammer springs and a hammer lock on the trigger body; hammer block right and hammer block left connected to the hammer right and hammer left; a trigger group main body formed within body tail on the superposed shotgun body and a trigger group main body where the trigger body is mounted with the trigger body opening switch.”

Another example relating to said embodiment is the utility model with application no. 2009/01142 and with title “superposed shotgun with superimposed two barrels having a magazine”. In the abstract of the invention with classification F41C 7/00 the following description takes place: “A frame in the operation system of the posed shotgun with superimposed two barrels having a magazine; an automatic safety part operating by the movement of the lever which is connected to the frame; lock holding the barrel rest operating within the receiver under the lever; a trig mounted onto the cover operating in the slot opening to the lock; a cover where the trig is secured and the slide spring operates; a slide which is brought to the slit within the lever which lowers the hammers; a spring operating between the slide channel and the cover; an ejector pin pushing the ejector holder by being attached to the hammer, an ejector holder which holds the ejector; a handguard where the ejector holder is secured and an ejector ejecting the cartridges.
